SCREENING DEVICE FOR POCKET-WINDOWS.

Specification of Letters Patent.

Patented Mar. 12, 1918.

Application filed March 9, 1917. Serial No. 153,708.

T 0 all whom it may concern Be it known that I, EDMUND H. LUXKEN, a citizen of the United States. and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful improvements in Screening Devices for Pocket-Vindows, of which the fol lowing is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to screens for windows having a wall pocket to receive all of the sashes, of the type wherein the screens are adapted also to pass into the pocket.

In devices of this character there are many difficulties in structurally arranging the screens, the sash and the pocket so that there are no unprotected openings left for access of dust when the windows are closed, in providing mounting means for the screens which permits of easy'removal for repairs and adjustment, and also in providing for proper adjustment of the parts with relation to each other, so that a practical screen device will be provided. Also there is necessity in this art for simplicity of construction so as to bring the obvious advantages of pocket windows and pocket screens within the range of standard practice in building construction,

such that they can be installed by the ordinary builder and carpenter.

It is the object of this invention to provide a simple practical screening device for pocket windows wherein the above difficulties are well done away with. and said object is accomplished by that certain construction and arrangement of parts to be hereinafter more specifically pointed out and claimed.

In the drawings,

Figure l is a longitudinal section taken through a window, showing the complete device.

Fig. 3 is a horizontal sectional detail on the line 3, 3, of Fig. 1.

section of the window stile, showing the adjustable mounting for the outer channel support.

Fig. 6 is a detail perspective section of one 7 of the screens.

The window is shown as having stiles 1, a sill 2 and a cap trim 3 and a wall pocket 4.- located above the cap trim. The lower sash 5 and the upper sash 6 of the window are adapted to pass entirely into the wall pocket and are provided with the new and useful of the window and seat at the upper end in a socket 10 at the top of the pocket. The screen channel 11 is mounted on thisguide rail and mountably removable with it.

For mounting the guide rail and channel it is merely tipped up into the pocket with its upper end in the socket at the top thereof, and then screwed to the stile of the frame at various points in a manner to be described. The channel has a plug 11 in the top to make an easy fit in the socket. The guide, rail might be screwed down in any usual manner. but it is preferred by me to have it adjustable laterally so as to take up inequalities in construction and make the fit of the window sash tight and snug.

Accordingly the guide rail is cut with laterally widened slots 12 (Fig. 5) for the attaching screws 13. and the screen channel member is screwed to the stile by passing the screws through these slots, thereby screwing down the guide rail at the same time. \Vhen it is desired to adjust the guide rail the screws may be loosened, theguide rail tapped over to the desired position and the screwstightened down again.

above the meeting line of the screens when mounted, and is adapted to be removably mounted as an insert in the channel by screws 15. I

There is a lower screen 16 and an upper screen 17 the lower screen being provided with a removable extension molding piece 18 soas'to' interlock with the moldings of the upper screen when in place (Fig. 1). The

upper screen is provided at its upper end witlra moldingextension piece. 19, whichis the- -full, size;of the; channel and slides; int-he channel, which is not the case with the lowerscreen extension piece.

The channel member is provided at--its lower; portion with a filler strip 21), which runs from the bottom of the channel up to the point where it, is desired to have the lower molding of the upper screen when the window screens are in place. This filler pieceis thesizew of-one of the screen mold-. ings, and, therefore provides a snug half sized channel which will fit the molding of the lower screen, it being remembered that thetchannel is twice the size of the screen moldings as above stated.

Itcan be realized that this channel con-'- struction is very simple and compact and easilyassembled. My application for patent Serial No. 148-030, filed February 12, 1917,

shows a somewhat similar construction, and

weather strip 22. The weather strip bears against the extension on theupper screen when the screens are down, and more important still-bears against the lower molding of the lower screenwhen the screens are in the poclget However in this instance there-are set inthis molding 21, small ferrule like pieces 23 which are slotted for the attaching screws 24: The screws may thusbe employed to permit lateral adjustment'of this molding so as to adjust somewhat the posi-- tion of the weather strip or take up its wear.

Mounted on the outside'trim- 25 of the window, at the base of the pocket, are sw nging catches 26 which can be swung into the path 'o'fthescreens and thus hold them up in the wall pocket. The catches are the 7 size of the screen channel andthus close up the'ispace leftby'the channel when the-lower screen and upper screen are both up in the 6%) pocket. When not in use the catches may be swung out of the way, as shown in dotted lines at A in Fig. at. It should be noted that the channel pieces are provided with a slot 28 which permits the catch to swing into position tohold the screens, and which support the catch when the screens are above it.

The catch when in useputs practically no strain on its pivot.

' For compensating screens, theyVare-provided with the usual springs 27 to slide in the channeL-and tend for the weight of-the" frictionally to hold the screens againstmove;vv r ment. In other ways the device shown in p the drawings is similar to that of my application aboverefer-red to,'which need not be: described, sincethey form no part oft'lllS".
